Computation of properties used in computeConnectionPressureDelta
is factored out to computePropertiesForWellConnectionPressures
The motivation is to be able to use a modified version of
computePropertiesForWellConnectionPressures in the solvent model
The following changes are done in order to remove the duplicated code in
assemble().
- extractWellPerfProperties takes SolutionState as input (only used in
the solvent model)
- the computation of effective parameters is moved to computeAccum()
With these changes the solvent model can use assemble() from the base
model.
The Todd-Longstaff model is extended to incorporate pressure effects
The solvent viscosity is then caculated as
mu_eff = mu_s^(1-\alpha * \omega) * mu_mix^(\alpha * \omega)
where \omega accounts for the porous media effects and \alpha =
\alpha(pressure) accounts for the miscibility of the solvent and oil
when contacted.
The \alpha values can be given using the TLPMIXPA keyword
If no entries are given to TLPMIXPA the table specified using PMISC will
be used as default.
IF TLPMIXPA does not appear in the grid \alpha = 1 and the pressure
effect is neglected.
This is tested in test_solventprops_ad.cpp
The well potentials are caculated based on the well rates and pressure
drawdown at every time step. They are used to calculate default guide
rates used in group controlled wells.
well_perforation_pressure_diffs is stored in
WellStateFullyImplicitBlackoil as it is needed in the well potential
calculations.
Enables flow to accept a basename for a case by appending a .DATA suffix
should it not be provided. It already supported reading the basename
from a .DATA extension file, but not opening said file by handing it to
the parser.
- The initial rates are only set to target values for single phase
producers (orat, wrat, grat).
- For injectors compi is used to determine the initial target rates.
The relative permeabilty endpoints are scaled by the miscibility
function. The endpoints is not supposed to be negative therefore all
negative values are replaced by zero.
the typo was caused the surface density of the oil phase to be used
instead of the one of gas. This caused the density to be off by a
factor of typically about 900.
using saturated FVFs does not change much, but it does not hurt
because it is also done that way in the simulator.
This makes the defaults for the threshold pressures reasonable again,
but for some reason they are not exactly the same as in the old
implementation. (although the differences are very tolerable.)
On the question why only "Model 2" is affected by this: the other
decks don't use threshold pressures (SPE-X) or do not default any
values (Norne).
A power method where both f and g are ADB variables is added
using the general derivative rule
(f^g)' = f^g * ln(f) * g' + g * f^(g-1) * f'
Tests are added to test_block.cpp
